Los Matachines & Shopping for Fangs

Hi Group,
Need help in locating distributors for these two videos.
Los Matachines by Paul Espinosa is distributed by Exceptional Videos but
can find no distrib. listing for them.
Same for
Shopping for Fangs by Quentin Lee and Justin Lin distributed by Marginal
Films (1998)
Also any info on locating 100% (or One Hundred Percent) by Eric Koyanagi.
